Traffic noise in a roundabout way
Abstract
A scale model and a calculation model were developed to predict traffic noise. The advantage of a scale model is that many different alternatives can be easily studied without high costs. The disadvantage is that materials properties have to be imitated according to fixed scaling rules and that the frequencies have to be increased by the scale factor. The scale model is very important in the planning of new roads and the reduction of noise, and for the improvement of calculation models. Legally prescribed calculation models were further improved in the sense that the sound waves are more closely followed. This model TOMAS is especially suited to study the interaction between the ground and noise screens.
